APPARATUS FOR DECORATING GLASS.

SPECIFICATION forming part of Letters Patent No. 513,180, dated January23, 1894.

Application filed December 23, 1890- Serial No. 375,656- (No model.)

To 02% whom it may concern:

Be it known that I, FRA'NZ EMIL GNAn'r, a resident of Munich, Bavaria,Germany, have invented certain new and useful Improvements in Apparatusfor Decorating Glass, of which the following is a specification.

This invention relates to an apparatus for producing, in quantities,plastic and gobelinlike ornamentations upon glass.

By this invention all the delicate shades and outlines may be producedin a simple and effective manner. 7

The invention consists in the various features of improvement more fullypointed out in the claims.

In the accompanying drawings,Figure 1 is a side'elevation of my improvedapparatus; Fig. 2 a plan or top view thereof; Fig. 3a section on line y,y, Fig. 2; Fig. 4 a top view of the frame on; Fig. 5 a section on lineas, at, Fig. 4. Fig. 6 is a vertical central section through cylinder dThe letter a, represents the work table, free to be reciprocated uponrailsb, of the machine frame A. The work table carries the frame m,hereinafter described, that holds the glass to be ornamented andsubjects it to the action of the brushes. Three kinds of brushes areemployed, viz: a cylinder brush 0, disk brushes (1, and reciprocatingbrushes e, e. The cylinder 0, receives its motion from the work shaft a(driven by hand wheel a or otherwise) by means of the pulleys a 0. andbelt a, and may be thrown out of action by shifting the belt in theordinary manner. The cylinders cl containing the brushes (1 moreparticularly employed for making round and oval patterns, are so placed,that they cover the entire width of the work (Fig. 2). They are driventhrough the bevel gear a, a, upright shaft of, gearing a a the gearwheels 01, being mounted upon the shafts a of the cylinders d Thecylinders d (Fig. 6) are open at the bottom and contain flanged heads dto which the tufts or brushes d are removably attached, by means ofscrews (1 passing through slits d of cylinders d". The heads cl arerendered vertically adjustable by set screws 01 so that the tufts may bemade to act upon the work with varyingdegrees of pressure. The brushesmay be of any suitable kind, and if an enamel coating is to be appliedto the work, a distributing brush is substituted. When tl1e brushesare'to be put entirely out of action, the set screws 01 are revolveduntil the tufts are drawn sufficiently into the cylinders. Thereciprocating brushes e, e, work at right angles to each other. They areguided by the rails (1. a and receive motion from work shaft 0., asfollows: Bevel gearing a, 0. transmits motion to crank shaft a thatimparts motion to brush e, by pitman a". By bevel gearing a, a, theshaft 00 is intergeared with crank shaft a having two pitmen (1. thatoperate brushe. If desired, the machine may be driven by a motor thatrevolves crank shaft a by pulley 0. Either of the brushes 6, 6, may bethrown out of action by disconnecting the pitmen a a from the crankshafts 0. a and drawing the brushes bodily out of the machine, or thesebrushes may be constructed similar to the brushes (1. They pass over thework laterally and longitudinally, covering a square at a time, and areparticularly adapted for hatching. The groups of brushes should becovered up during action, so as to prevent the finely divided color fromflying away.

The glass to be ornamentedis either cut up into the required form or isintroduced into the frame m, in plate form. This frame 1s made from drywood and is encircled by the angle iron m. It is provided with upwardlyand downwardly projecting pins 12., for holding the stencil plates andthe bottom plate. For locking smaller pieces of glass, the frame m, isprovided with a net work 0, of intersecting ribs, each rib having ahorizontal flange 0', for supporting the glass.

To place the glass 19, into the frame, the latter is put into thereverse position from that shown in Fig. 5, t'. a, it is so placed, thatthe flanges o, are at the bottom and that the glass 19, may be placedupon such flanges. Upon the glass 19, small wooden disks or blocks q,are placed, having a felted face q, that bears gently upon the glass. Anumber of springs g are now so placed upon the blocks, that a pair ofcrossing springs gently press on each block. Finally, a bottom plate ois attached to the frame m, by means of the pins n, that engageperforations in the plate. Small Wedges 17., hold the plate in place.The frame thus filled, is now turned into the position shown in Fig. 5and placed upon table upon which itis held by suitable stops.Distributing brushes being substituted for the brushes d, and themachine being set into operation, a coating of black enamel color isfirst applied to the work. The stencils s are now placed upon the framem, (Fig. 5) one after another and with each stencil the work is passedthrough the machine. The stencils are, of course, so chosen as toproduce the desired outline effect and shades According to the nature ofthe design, either of the brushes is put into or out of action. Thuseither the brush 0, or the brushes d, or the brushes e, e, may be putinto action, or either two or all three sets of brushes may be usedsimultaneously to removepzirtly the paint exposed hrou t 's b'nc p a' e-If it is desired to produce the design in a plastic form'and in shadesand not only in outline,the pattern may be "firstburnfed or worked intothe glass and the "glass may be wa r"! th 9 y h ach e T p11 d'ucethiscoating the brush a, is removed," the brushes e,'e',areput out oraction and the et rushe re ken t an replaced by distributing heads. Thecolor is b Q?! t r a d e at e pas ed. ii 'u h mac i e fr m whi w iemr ei111iformly coated. After a sufficientql ai tify of the glass has beenthus prepared, the main brushes are again set into action to produce thedarker shades in the designs. In order to produce the half shades andthe l1g ht shades, the glass is covered at its third 1ntroduction, witha thin oil color, which does not eitect the design so far produced.

After completion, the glass will be beautiul y Q em n ed, wi h h pi t inlight and shade and in the nature of a gobelin.

Of course the quality of the work may be readily changed by using alarger or smaller number of stencils. Before the glass is burned in themuffle, its back maybe covered with a suitable tint.
